Hello everyone. After 32000 faultless fun miles in my 100, she finally showed herself up last week when the engine light lit up. A friend has one of those diagnostic readers and the fault shows up as P0130..generic 02 Sensor Circuit Malfunction (Bank 1 Sensor 1). This is in the handbook that comes with the device so I'm not sure if this is similar to a Fiat reader. Would anyone have any idea as to what the problem might be? She seems to be slightly sluggish/rough but that might be my imagination. I can't get it looked at until next week so I was wondering whether anyone can give me a heads up as to likely costs etc. Thanks very much in advance.
